Disconnect the throttle position sen-sor coupler from the throttle positionsensor.b. Connect the pocket tester (Ω × 1k) tothe throttle position sensor.c. Measure the throttle position sensormaximum resistance.d. Calculate the throttle position sensormaximum resistance when the throt-tle is fully closed.Example:If the maximum resistance = 5 kΩ, thenthe throttle position sensor’s maximumresistance when the throttle is fullyclosed should be:5 kΩ × (0.13 ~ 0.15) = 650 ~ 750 ΩLift the throttle body assembly slightlyout of the intake manifolds.Loosen the throttle position sensorscrews 4.Connect the pocket tester (Ω × 100) tothe throttle position sensor.e. Adjust the throttle position sensorangle so that the measured resistanceis within the specified range.After adjusting the throttle position sen-sor angle, tighten the throttle positionsensor screws.s s s s s s s s s s s s s s s s s s s s s s s s s s sPositive tester probe →blue terminal 1Negative tester probe →black/blue terminal 2Throttle position sensor maximumresistance (throttle is fully closed) =Maximum resistance × (0.13 ~ 0.15)Positive tester probe →yellow terminal 3Negative tester probe →black/blue terminal 2Throttle position sensor resis-tance650 ~ 750 Ω(yellow — black/blue)B/L Y L2 3 144
